Changchun is the capital of Jilin Province, located in the northeast of Songliao Plain, the total area of ??20,604 square kilometers, under the jurisdiction of a county District 7 2 cities, with a total population of 7.67 million. Changchun is the political center of Manchukuo period of history, and therefore retain more historical relics Manchukuo period buildings, but also the new China Changchun Automobile Industry, optoelectronics, biotechnology, chemistry, the birthplace of the film industry [1-2] and has received the honorary title of national civilized city, state health cities. River gravel crusher is suitable for crushing river gravel Sand soft or medium hard and extremely hard materials, plastic, widely used in a variety of river gravel, pebbles, minerals, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and various metallurgical slag, especially for silicon carbide, silicon carbide, sintered bauxite, the US high sand hard, extra hard and abrasion resistance than other classes of materials ... Product details River gravel Sand machine is suitable for crushing soft or medium hard and extremely hard materials, plastic, widely used in a variety of river gravel, pebbles, minerals, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and a variety of metallurgical slag, especially for silicon carbide, silicon carbide, sintered bauxite, the US high sand hard, special hard and abrasion resistance material is higher than other types of sand making production efficiency. Product Name: River Sand Pebbles! Such new Sand crushing ratio, the expected size adjustable, stone molding 5mm or less in size up to 85 percent, the daily processing 200T can be easily achieved. Can be called "Sand King" efficient crushing machine is a new device. 800 × 400,800 × 600,800 × 800,800 × 1000 efficient Sand, Sand reference to integrate various types of new technology design works, and its typical use is to adapt to the current artificial sand industry, is the cone crusher machine, rod mill crusher, impact crusher, sand making straight-through upgrading of the new fifth-generation products. Features a river gravel crusher, deep cavity type rotor design is optimized, so that the material throughput increased by about 30%. 2 weeks shield can wear down a U-turn after topical use, improve material utilization, can improve the life of more than 48%. 3, modular design hammer, hammer part simply replace worn, can reduce the cost by more than 30%. Also increases the hammerhead, effectively prevent damage after the main hammer wear vertical plate. 4, the most important core of wear-resistant materials used by the US industries with highly wear-resistant high-temperature materials. 5, using diamond impact block, avoid the vertical plate material impact abrasion damage. 6, bearings used in Japan, Sweden, the United States and other international brands. 7, the optimal transmit port and internal smoother curved design, reduce the flow resistance of the material, greatly improve the capacity of the material. 8, dual bulk tray, simple, convenient way to achieve the two feed conversion. 9, the lower end of the spindle special sealing structure to ensure that no seal is not leaking. 10, Japan imported parts hydraulic lid device can be convenient and efficient mobile cover, so that the body's internal overhaul replacement parts saving labor 11, the selection of high protection class motors. This type of motor has a high efficiency, low noise characteristics. In line with the International Electrotechnical Commission (IEC) standard, F class insulation, IP54 / 55 protection rating.
